FUELSPRAYER.

= To all whom it may concern 'means of a current of com Dressed air thus producing a mixture of ne particles of fuel and air.

According to the present invention a valve is provided which is normally held against its seat by a constantly acting pressure such as is produced by the action of a spring or weight, this pressure serving to prevent the valve from being raised olf from its seat by any opposing pressure, until it is actuated by the proper means at the vproper time.

In my invention thefuel is supplied to the device by means of a suitable pressure pump, not illustrated, in the drawing, since it comprises no part of my invention. This pump is adapted to produce a pressure Asufficiently great to overcome the pressure which holds the valve above mentioned normally seated and forces the 'fuel into the fuel chamber Where it comes into Contact with a current of compressed air by 'means of which it is sprayed-into the combustion chamber of the engine.`

In the drawing annexed hereto and forming a part of this application, and in which I have illustrated one preferred embodiment of my invention, the figure shows a longitudinal cross section view of the pre ferred form of my invention.

A. compressed air chamber a leads to the combustion chamber of the engine and has disposed therein in axial alinement, the hollow sleeves ci and c, in the bore of which is disposed the regulating valve spindle eoacting with the valve seat c in the sleeve c and a rear annular valve seat c on the sleeve a coacting with the vertically recipro eating spindle d. The annular mouth a in the channel e surrounds the end of the regulating spindle which end is preferably conical in shape. A spring e is disposed in the Specification of Letters Patent.

air channel a and se ves to keep the vulve spmdle `d tightly pressed. against the valve seat cl with sul'licient pressure so that the said valvecan only be raised from itssest by a. counteructing pressure eater than that of the spring ,./iroiuid is disposed a liuel chamber channel It leads thereto el channel being normally closed by a vulve which acts as a check valve against `')ressure in the fuel chamber The entrance ol' 1'." to the chamber f is controlled by the said check valve g which, as before stated, is adapted to be actuated by the g i the fuel in` the channel il., seitl being produced by any as a pump, so that the iuel is into the chamber f end then into the passe a at a pressure su'liicient'to overcome 'the pressure produced by the compr of the internal combustion enwine with which the device is used. It isv therefore obvious that the supply of fuel entering the chamber f is controlled by the valve g.

The check valve g, as before set forth, actuated by fluid pressure, and the spindle the lower part of which constitutes valve, is moved by means of e com or other device not shown, which is actuated und forced through the valve g into the e' cui rent passing through the channel e, "wl e the spindle is raised.

It is to be understood that I not limit myself to `the exact construction and, zu rangement of parte herein set forth., but muy resort to such modificati-fuis as fall within the scope of my. claims.
